I asked about this myself, because I'm a big VC-64 fan. Plug-ins can be a source of instability in all programs, and especially, running old 32-bit programs in a 64-bit environment can be problematic - which is why few 64-bit DAWs also offer 32-bit support out of the box. Cakewalk has done what I feel is reasonable - dropped certain plugs from new installs, but still have them available for custom installs if you want them. After all, the FX tape sim makes a fine white noise generator
